Copper Leaching Plant Design

Leaching Plant Design Mineral Processing & Metallurgy

Leaching plants, faced with increased tonnage, coarse (up to —3/16″ solids) feed, longer retention time, erosion, corrosion and the high cost of space, must be compact, simple and highly efficient. The engineer faced with the obvious economy of using a few large agitators compared to many smaller units must also evaluate the design factors which will prevent the settling-out of solids
